Water pan and heat pump dryer comprising same

Abstract

The invention relates to a water pan and a heat pump dryer comprising same. The water pan comprises an upper pan and a lower pan, and the upper pan is positioned above the lower pan; the upper pan isused for receiving condensed water separated out by the dryer, the rear end of the upper pan is provided with a water falling hole, and the bottom surface of the upper pan is inclined downwards towards the rear; the lower pan is used for receiving condensate water flowing out of the water falling hole, and the bottom surface of the lower pan is inclined downwards towards the front; a containing cavity capable of storing condensed water is formed in the lower pan, and a heat exchange tube is arranged in the containing cavity. According to the water pan and the heat pump dryer comprising the same, the latent cooling capacity of the condensed water can be fully utilized, so that the purpose of reducing the energy consumption of the dryer is achieved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a water receiving tray and a heat pump dryer including the water receiving tray. Background technique [0002] For general heat exchange devices, such as dryers, the refrigerant inside the evaporator is in a state of evaporating and absorbing heat when it is working, and the surface temperature of the evaporator is low. When the air contacts the surface of the evaporator, the air temperature drops. Liquid condensate will precipitate at the dew point temperature. [0003] In general water-cooled coolers, the cooling water flowing into it is generally tap water or reclaimed water obtained from sewage treatment. The outdoor ambient temperature is also lower than the temperature of the outdoor cooling water source. [0004] From the existing experience, when the evaporation temperature is 10°C~15°C or lower, the temperature of the condensed water is 15°C~20°C. When the ambie...

AI Technical Summary

Problems solved by technology

If the condensed water is directly drained, the cooling capacity hidden in the condensed water will be wasted, which is equivalent to the loss of some energy consumption of the dryer.

[0005] The existing technical solution for recycling the implicit cooling capacity of condensed water is to pump the condensed water to the spray system through the water pump, and spray the condensed water to the equipment that needs to be cooled through the spray system, but the process of spraying the condensed water through the spray system The intercooler consumes a lot, which has poor cooling effect on the equipment, and also increases the installation cost and maintenance cost of the sprinkler system
